4 Claims.

Where it .is desired to interleave one or more sheets of paper with other sheets, as when carbon paper is interleaved with record sheets to produce several copies of a record, it has hereto-- fore been necessary to raise each record sheet individually and carefully place a carbon sheet beneath it, aligning it with the record sheets above and below it. This requires separate handling of each carbon sheet, the number depending upon the number of record copies to be made, each time the carbon sheets are inserted and removed, and results'necessarily in smudging and otherwise mutilating the carbon and record sheets, soiling the fingers, and wasting a great deal of time.

It is accordingly an object of this inventionto provide a manifolding sheet of improved con-- struction, which may be easily interleaved in a minimum of time between other sheets of. paper, without soiling the fingers or smudging or mutilating the sheets.

It is a further object to provide an interleaving guide which may be used in simultaneously interleaving several sheets of carbon paper with record sheets, in aligning and straightening the sheets, and in stripping or removing the sheets from interleaved relation.

For a fuller understanding of the invention, reference should be had to the accompanying drawing, in which a Figure 1 is a plan view of a record book having transfer sheets, embodying features .of my invention, interleaved with the sheets of a record book and with the uppermost record sheet partially broken away;

Fig. 2 is a sectional view taken in the direction of the arrows on the line 2-2 of Fig. 1;

Fig. 3 is a perspective view of three transfer sheets having my improved interleaving guides applied to one edge;

Fig. 4 is a perspective view of one form of my interleaving guide;

Fig. 5 is a perspective view of a clip or fastening device which may be used in assembling my improved manifolding sheets, and

934, Serial No. 724,165

In the accompanying drawing, the numerals I, 2 and 3 indicate sheets of transfer material, such as carbon paper, to one edge of which are secured, as by means of a suitable adhesive, interleaving guides 4, 5 and 6, formed of narrow 5 strips of relatively stifi material, such as cardboard, heavy paper, or fiber, and which preferably are slightly longer than the carbon sheets, and have ends I, 8 and 9 extending beyond the edges of the carbon sheets as shown. The projecting ends I, 8 and 9 serve as finger grips or handle members and for convenience they may be slightly broader than the remainder of the strips 4, 5 and 6 as shown. However, it is to be understood that these ends may be made the same width as the body portions of the strips. The other ends of the strips extend to the opposite edge of the carbon sheets, but are preferably so formed that when they are assembled in superimposed relation, as shown in Figs. 1, 2 and 6, they are in progressively staggered relation to each other from the lowermost strip to the uppermost strip. Thus, as shown in Fig. 3, the end of the lowermost strip 4 is disposed at right angles to the side of the strip, as shown at H]; the end of the next strip 5 and of the carbon sheet 2 are formed with a small inclined or diagonal portion ll, while. the end of the uppermost strip 6 and of the carbon sheet 3 have a large diagonal or inclined portion l2.

When it is desired to interleave but a single transfer sheet between two record sheets, a carbon sheet having my interleaving guide secured to one edge, maybe used alone. However, when it is desired to interleave several transfer sheets between several record sheets to produce several copies, then the transfer sheets are arranged so that they and the interleaving guides are in superimposed relation and so that the ends H], H and I2 of the interleaving guides are stag,- gered progressively. with respect to each other asshown in the accompanying drawing. The projecting ends 1, 8 and 9 of the interleaving guides will then be superimposed and in registry with each other and may be secured together by means of a suitable fastening device, such as the metal clip [3, which is formed with a lower plate l4 having upturned tongues l5, and an upper plate IS with apertures H. The fastening device may be folded around the endsl, 8 and 9, so that the tongues l5 project through the ends into the apertures H, as shown in Fig. 2.

The transfer sheet assembly thus formed may be conveniently interleaved with the sheets of a record book. In Figs. 1 and 6 a record book I 8 is shown, having leaves I9, 20, 2| and 22 with any desired form printed thereon and bound together at one edge, as at 23, by suitable means, such as the staples 24'. The book, of course, may be of any conventional type and may be formed with lines of weakening so that the sheets may be conveniently removed from the book.

For the sake of illustration, it is assumed that it is desired to make an original and three copies of a record. Accordingly, three transfer sheets having the improved interleaving guides along one edge, are assembled as described above, with their ends II), II and I2 arranged in progressively staggered relation, and with their ends 1, 8 and 9 secured together by the clip l3. The cornersof the first three pages of the record book are turned up as by means of an eraser held in the right hand and are held separated near the corner by insertion of the first three fingers of the left hand. The projecting ends 1, 8 and 9 are then gripped between the thumb and forefinger of the right hand, the end I ll of the strip 4 being inserted between sheets l9 and 20, the end ll of the strip 5 being inserted between sheets 20 and 2|, and the end l2 of strip 8 being inserted between the sheets 2| and 22. The first three fingers of'the left hand are then removed from between the sheets of the record book and by-moving the assembly in the direction of the arrow in Fig. 6, all of the carbon sheets will simultaneously be brought into proper registry with the record sheets, as shown in Fig. 1,- with the ends 1, 8 and 9 projecting beyond the side edge of the record book H3. The carbon sheets may readily be shifted to any desired position between the record sheets.

To strip the record book of the carbon sheets,

all that the operator has to do isto grip the projecting ends 1, 8 and 9, and by a simple downward or outward stroke, remove the carbon sheets from interleaved relation with the record sheets; If so desired, the first three sheets of the record book may be gripped with the carbon assembly and removed simultaneously with it leaving the last copy bound in the record book.

While in the accompanying drawing my improved interleaving guide is shown in association with transfer sheets, it is understood that it may be applied to any type of sheets which it is desired to interleave with other sheets, and it is to be further understood that sheets to which my improved interleaving guide may be applied may be used separately or in assembly with any desired number of other sheets to which interleaving guides have been similarly applied.

I claim:

.1. A device of the character described comprising, in combination, a plurality of superimposed manifolding sheets, strips of relatively stiff material secured to one edge of said sheets and superimposed with relation to each other, said strips projecting beyond the manifolding sheets at one end and havingtheir other ends disposed in progressively staggered relation, and

means for securing the projecting ends of said strips together.

2. A device of the character described comprising, in combination, a plurality of superimposed carbon sheets, strips of relatively stifi material secured along one edge of said carbon sheets, said strips having ends projecting beyond an adjacent edge of 'said carbon sheets and having their other ends diagonally disposed and arranged in progressively staggered relation to each other, and means for securing said projecting ends together;

3. An interleaving gui de including, in combination, a plurality of superimposed strips of relatively stiff material, handle portions formed at one end of said strips, the other ends being arranged in progressively staggered relation, and means securing said handle portions together.

4. A device of the character described comprising in combination, a plurality of superimposed manifolding sheets, strips of relatively stiff material secured to one edge of said sheets and superimposed with relation to each other, said strips projecting beyond the manifolding sheets at one end, and having their other ends disposed in progressively staggered relation.
